Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements, performance criteria and range of conditions on at least one occasion and include:
inspecting and evaluating safety and functionality compliance of the switchboard accurately following established procedures to obtain approval to rectify non-compliance aspects of the switchboard carrying out preparation work effectively rectifying compliance defects placing and securing metering correctly making power and communications connections in accordance with manufacturer specifications and functional and regulatory requirements setting meter parameters in accordance with manufacture’s specifications and functional and regulatory requirements reinstating supply to the installation safely documenting current transformer (CT) metering and rectification work and notifying appropriate persons in accordance with established procedures dealing with unplanned events applying relevant work health and safety (WHS)/occupational health and safety (OHS) requirements, including using risk control measures applying sustainable energy practices completing activities following quality, workplace procedures and instructions preparing, installing and replacing CT energy metering selecting metering and CT components using tools, equipment, personal protective equipment (PPE) and testing devices reporting work activities.

Knowledge Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements, performance criteria and range of conditions and include knowledge of:

Assessment Conditions

Assessors must hold credentials specified within the Standards for Registered Training Organisations current at the time of assessment. Assessment must satisfy the Principles of Assessment and Rules of Evidence and all regulatory requirements included within the Standards for Registered Training Organisations current at the time of assessment. Assessment must occur in similar workplace operational situations where it is appropriate to do so; where this is not appropriate, assessment must occur in simulated similar workplace operational situations that replicate workplace conditions. Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate. Resources for assessment must include access to: a range of relevant exercises, case studies and/or simulations relevant and appropriate materials, tools, facilities, equipment and PPE currently used in industry applicable documentation, including workplace procedures, equipment specifications, regulations, relevant industry standards, codes of practice and operation manuals.
